The Mega Tesla is a defensive building in the Builder Base that unlocks at Builder Hall level 8.

It is a defense that can damage both air and ground troops.

The Mega Tesla attacks with chain lightning; the electricity it fires damages a first target within the range of the Tesla, and then, if possible, the bolt will arc towards a second target up to 3 tiles away from the first target and damage it as well.

Defensive Strategy

The Mega Tesla deals high damage, but has a low fire rate. It is good to protect it using splash-damaging defenses and traps, such as the Roaster, Crusher, and Mega Mines, to prevent enemies from distracting it with lower-hitpoint troops.

The Mega Tesla's Chain Lightning can chain onto a Sneaky Archer under her cloak and kill her, provided that it has another nearby target to attack first.

Offensive Strategy

Try to swarm your opponent's base with Barbarians after breaking into the base so your other troops, like the Battle Machine, can stay safe.

Drop Ships can tank several shots from the Mega Tesla and drop skeletons to distract it.

The description of the Mega Tesla has a grammatical error, saying "It's powerful jolts..." instead of "Its powerful jolts...".
